A novenquadragintillion or novemquadragintillion is equal to \(10^{150}\) or \(10^{294}\) in France and Germany by Conway-Wechsler system.[1][2][3][4][5] Novenquadragintallion is an original name by Conway and novemquadragintallion is a simplified name or Jonathan Bowers system.[6]

In the long scale which is commonly used in France and Germany, \(10^{150}\) is called quinvigintillion.

Aarex Tiaokhiao gave the name pentigintillion, referring to the value of this number.[7]

Wikia user NumLynx gave the name quinquagintisand for this number's short scale value.[8]
